Intelligibility of Reflected Sound Sources Part I

A comparison of the speech-intelligibility of the reflected signal from a vs. a human voice, in a highly reverberant environment. The study was made both with subjective judgement methods and by using the standardized measuring methods commonly used,i.e.RASTI-STI-Alcons-C60-C80. The conclusion points out the possibility to distribute information in a reverberant room by exiting the reflective field in the same manner a purely acoustic source does-i.e. a human voice or an musical instrument.
